Take Me Out host Paddy, 45, said he'd dropped from 14st to 12.5st in 2017 and had "totally forgot" to show off the results before Friday.

Hours later, topless Keith, also 45, also shared side by side snaps and flashed a confident stare as he sucked in his belly.

He captioned his photo: "Totally forgot to post this last year. This a before and after pic of four months of doing nowt, eat just the same s**t as always, apart from no bread.

"Never eat bread! I really enjoyed it but definitely could’ve got a bit leaner but I cun’t be bothered. Before I was a waist 34” and still am but I feel fit and strong. @mcguinness.paddy you are an inspiration to me. I’m gonna keep it up!"

Alongside his before and after images, he wrote: “Totally forgot to post this last year! This is a before and after pic from the 4 months of good diet and training I did.

“I really enjoyed it and definitely could have got leaner but I began to feel a bit to thin. I started at 92.7kg and finished at 78.7kg. I got down from around 26% body fat to 12% and went from a 36” waist to a 32”!”

The dad-of-three continued: “I’m now somewhere in between these two pics shape wise, probably more to the first one after Chrimmy! I still enjoy training but I don’t fancy stripping that much fat again.
